Please enlighten me.

I'm In the works to buying a new Turbo for my freshly rebuilt and BIG streetported s5 TII. I generally have the foundation to build a FC that I want to put down 400hp. ie. FMIC, Standalone, bigger Injectors, Exhuast etc. I'm not striving for anymore than that. With my gathered facts on this Turbo, I'd like to know If It can have the potential to create this kinda HP and If I am missing any additional facts that may seem relevant. Additional details on this Turbo would be an asset!

-Turbonetics TO4E 60-1
-Double Ballbearing
-Big Shaft Option
-Exhuast A1.15
-.96A/R

 

Tony, the 60-1 wheel is a to4b series wheel, if its a to4e, it will be a to4e 60 trim, which is a little different than the 60-1, I got rooked on that when I bought my to4e, I was told it was a 60-1 , further research showed me it wasn't.. When I had my turbo rebuilt, though, I asked if I could get the 60-1 wheel, its possible to put that wheel in the t04e, but from an economics standpoint its not worth the cost of the machining etc needed..
I also wanted to step up to a t66 using the t04e architecture, while again it was possible, it was not worth it either..
But that being said, I did make 400 rwhp on the t04e 57/60 trim setup, and on the same turbo, right now with my current porting and tuning changes, I think I am eclipsing that number now by somewhat... My intake air temps are up, so I know I am moving the turbo far out of its efficiency range..
My specs are
T04e 57/60 trim(Ford HD oem wheel)compressor
Standard bearings
.70 compressor a/r
p trim exhuast wheel
1.15 a/r exhaust

 

to4 e 60 trim map

 

Here is the 60-1 wheel, note the map location at 2.00 pressure ratio at 40lbs/min..(approx where one would find 400 rwhp)

 

Thanks for the detailed reply Max.

I've just learned that It Is a TO4B, It's a Q Trim and It Is not divided.

Correct me If I'm wrong, but does the TO4B out perform the TO4E In pressure ratio and overall more ***** to It etc?

 

Unless you've already Indirectly answered this.

 

hmm, q trim is kinda big undivided, especially with the 1.15/ar....
Yes the to4b will "put out" more than the t04e at certain pressures... The t04e is the newer architecture, and also what the other T-series are based on, but the 60-1 is a better choice than the to4e 60 trim..Max

 

What about a T04S 60-1?

 

a T04S is a 60-1

T04S=60-1

 

Actually only about half the time this is true. T04S is a compressor cover and not just a turbo. More often than not, a if you see a turbo and they are just calling it a T04S, then it is using a T58 compressor and not a 60-1. And, half the time people are running T58's and think they have a 60-1.

I've learned that the T04B and T04E have very close wheel specs with the "T04B flowing much more - partly due to the "B" width {b-width is blade highth}".

 

maxthe7man, can you tell me at all how your to4e compares to xs engineerings to4e kit? all i know is that i have an xs to4e kit. . . im sure ill be able to hit 400 rwhp, but i wanna know how the turbo feels about that. hahaha.

paul

 

I have never used an XS kit so I can't give you a comparitive judgement..
Its hard to describe how the car feels.
With a stock port motor, it had some lag, but then would hit hard around 3500 rpm..
I am now using a heavily streetported motor, it almost boosts like a stock s4 car now, Just a hint of lag, then a strong linear pull ... I dyno'd 365 rwhp with my old motor, the new motor is well over that..
My car has yet to be beaten up on the streets around here, even at default boost level of 8psi...I run 10 psi most of the time, and thats plenty fast for in city driving..
15 psi, is very strong.... The roof of my car is rippled now...Max

 

Tony is that turbo u are looking at Dry or wet chra? get wet.

 

I get a kick out of this everytime I hear It.


I will be Investing In a Turbo that has both Oil and Water Center Housing along with a 360 Thrust Bearing and Dynamic Seal.

 

I thought ball bearing turbos do not have thrust bearing

 

I would recomend against a Q trim, undivided 1.15 on the street. If you want 400 RWHP, a Ptrim is more than adequate and it will give you better spool. A .96 or 1.0 turbine housing will give you 400 as well, with more spool (and I made 470 with my .84, but it's a different breed of turbo) Also, divided has been shown repeatedly to give more boost response (with a divided manifold as well) in addition to more top end as well.

IMO, you will be better off running a 1.0 A/R divided housing with a P trim wheel if you are looking for 400 RWHP. This setup will do it with better spool ie more low/midrange than what you'll see with the large A/R Q trim setup...

If you want the best of both turbin wheel worlds then you need to consider a Garrett GTQ wheel. Spools like a P, flow like a Q, but probably isn't necessary for your app.

I bought the Wet and Dry. More lines to run but in the long run its better.

I have the undivided turbo. I went with the .96 to keep some bottom end. I think you would have a faster car if you have better low end grunt. 1/4" mile is when you need all the top end anyhow. On the track/street its not needed I would think.

I did not think you can get a divided T04B. Maybe I did ask for undivided T04B but thats what I got. HKS manifold was undivided anyhow!

Live and learn..........

 

I'm sketchy on that. If thats the case, I'll go with the former.

Roro, It turns out that It will be a P Trim rather than a Q. I've been misinfomed. Again!


Thats a good question. If the option Is available, I'd like to go with divided despite, the use of the HKS cast Manifold I will be using for now.

Does anyone know If the Turbonetics T04B 60-1 can be had divided?

 

haha, just in case you didn't know "roro" is my wife but I'm "carx7" and just didn't realize she was signed in .

Anyway, of course you can get a T04B with a divided housing. You can get it anyway you want it, it's just a function of what you want to pay for it.

I'd be kinda skeptical of purchasing a turbo from this person who has misinformed you, unless it was just a misunderstanding.... anyway.

Look for turbonetics.com which is actuallay precision techinques and they have a pretty good turbo catalog. You can see all your options there.

FWIW, turbonetics BB turbos are generally considered to be junk needing rebuilding frequently at a high expense and garrett turbo's are better IMHO. If you'd like the name the supplier that I used PM me (carx7)offline. He made me a great deal on my new Garrett turbo.

Well do Chris, I appreciate the helpful handout.

I do remember you cross-posting b'n user names before and Roro being the other.

At any rate, I need to go back to the drawing board before I even attempt to add further to this thread. Too many varibles right now.
